Answer 1

simplify the expression,

`4z+5z^2-z+z^2`

In order to simplify the expression, we need to group the like terms, like terms can be identified through the degree of the literal parts, in this case, we have expressions with first and second degrees,

`\begin{gathered} 5z^2+z^2+4z-z \\ 6z^2+3z \end{gathered}`
